Abstract In Iraq, the leafminer, is one of the most destructive pests of vegetables. Vegetable crops, such as squash Curcurbita pepo L. and tomatoes Solanum lycopersicum L were surveyed to record abundance and diversity of agromyzid leafminers and their natural enemy species. Population density of these pests were studied for the period from April to June 2014 in the College of Agriculture, University of Baghdad- Abu Ghraib. Two leafminers were detected, including Liriomyza bryoniae (Kaltenbach) on squash crop and Phytomyza horticola Gaureue on tomato crop. The results revealed that infestation by Leafminer, L. bryoniae and P. horticola were initiated on leaves situated on the median level of squash and tomato plants, then on leaves of lower level. Because, adults don’t tend to lay eggs on young leaves so that reflected on larval density on these leaves. The rate of larvae numbers of tested insect through the growth season showed that squash's and tomato's leaves of median level were more preferred for leafminer's larvae through the growth season.

We also studied the experimental restoration of psammophytic grasslands to compare the impact of two near-natural restoration methods (spontaneous and assisted succession) to establishment of target species. The sand pit comprises stages of 2 to 30 years since site abandonment with moisture gradient from wet to dry habitats. In all studied groups, i.e. vascular pants and arthropods, open spontaneously revegetated sites continuously disturbed by intensive recreation activities hosted the largest proportion of target and endangered species which occurred less in the more closed spontaneously revegetated sites and which were nearly absent in technically reclaimed sites. Out results provide clear evidence that the mosaics of spontaneously established forests habitats and open sand habitats are the most valuable stands from the conservation point of view. It has been documented that no expensive technical reclamations are needed to restore post-mining sites which can serve as secondary habitats for many endangered and declining species. The experimental restoration of rare and endangered plant communities seems to be efficient and promising method for a future large-scale restoration projects in abandoned sand pits.

The present investigation was carried out to study the parasitoid diversity of this pest in different agroclimatic conditions of Himachal Pradesh, India. Sixteen species of parasitoids viz. Diglyphus horticola Khan, Diglyphus isaea (Walker), Zagrammosoma sp., Pnigalio sp., Quadrastichus plaquoi Reina and LaSalle, Asecodes erxias (Walker), Closterocerus sp., Neochrysocharis formosa (Westwood), Chrysocharis sp, Chrysocharis indicus Khan, Pediobius indicus Khan (Eulophidae), Opius exiguus (Wesmael), Dacnusa sp. (Braconidae), Cyrtogaster sp., Sphegigaster sp. (Pteromalidae), and Gronotoma sp. (Figitidae) were recorded parasitizing C. horticola in different agro-climatic zones of Himachal Pradesh. Agro-climatic zone II (sub-temperate mid-hills) was the richest in parasitoid diversity (14 species) followed by zone I (11 species), zone III (7 species) and zone IV (4 species) which are characterized by sub-tropical sub-montane, wet temperate high hills and dry temperate high hills, respectively.

  • Effect of Distance to Urban Areas on Saproxylic Beetles in Urban Forests
    Effect of distance to urban areas on saproxylic beetles in urban forests Effekt av avstånd till bebyggda områden på vedlevande skalbaggar i urbana skogsområden Jeffery D Marker Faculty of Health, Science and Technology Biology: Ecology and Conservation Biology Master’s thesis, 30 hp Supervisor: Denis Lafage Examiner: Larry Greenberg 2019-01-29 Series number: 19:07 2 Abstract Urban forests play key roles in animal and plant biodiversity and provide important ecosystem services. Habitat fragmentation and expanding urbanization threaten biodiversity in and around urban areas. Saproxylic beetles can act as bioindicators of forest health and their diversity may help to explain and define urban-forest edge effects. I explored the relationship between saproxylic beetle diversity and distance to an urban area along nine transects in the Västra Götaland region of Sweden. Specifically, the relationships between abundance and species richness and distance from the urban- forest boundary, forest age, forest volume, and tree species ratio was investigated Unbaited flight interception traps were set at intervals of 0, 250, and 500 meters from an urban-forest boundary to measure beetle abundance and richness. A total of 4182 saproxylic beetles representing 179 species were captured over two months. Distance from the urban forest boundary showed little overall effect on abundance suggesting urban proximity does not affect saproxylic beetle abundance. There was an effect on species richness, with saproxylic species richness greater closer to the urban-forest boundary. Forest volume had a very small positive effect on both abundance and species richness likely due to a limited change in volume along each transect. An increase in the occurrence of deciduous tree species proved to be an important factor driving saproxylic beetle abundance moving closer to the urban-forest.
